WAIKELE (HawaiiNewsNow) - For the first time we're hearing the frantic moments as the Waikele bunker fireworks explosion was happening from the only survivor. The emergency call begins with the survivor yelling the names of the victims who were trapped inside the bunker. He then directs his attention to the operator. We want to warn you the audio can be painful for some to hear, especially the victim's families.

On April 8th the bunker storing confiscated fireworks exploded. Investigators are testing residue from inside and hope to release information in the next few weeks about what caused the blast. Five employees of Donaldson Enterprises were killed. There was one survivor, a supervisor who made the following call for help.

911 Operator: "What's going on?"

Caller: (Unintelligible) "They're stuck in the fire. The fire in storage they're all in there right now! They're getting burned right now!"

911 Operator: "Okay what's burning?"

Caller: "The bunker. The bunker is on fire, Waikele Storage. Please hurry up!"

911 Operator: "Okay we are on our way already sir. What is exactly burning?"

"First of all we want to apologize to the people listening, in particular to the family, this is not our normal standard. It's below our standard of how we process calls," said Capt. Terry Seelig, Honolulu Fire Department.

The operator who made the comment is a veteran of the fire department and he'll continue to be. He will not lose his job. The department would not comment on any disciplinary action.

"He is very upset at himself and how this was done," said Capt. Seelig.

Firefighters were already on their way and say the call did not slow their response time to the scene. The call is prompting changes within the department. All dispatchers will get additional training and regular guidance to make sure proper behavior is being met.

"We have literally hundreds of calls a day but all of them have to be handled the same way. That's what the training will focus on the right way to do things," said Capt. Seelig.
